Got a South Park and it was working pretty good. Turned it on one day and there was no sound. I started poking around and think it might be one of the caps (c114) on the cpu/sound board. I have a Starship Troopers so I will try to compare the two to see if I can narrow it down. Anyone have any ideas as to what it might be? There is sound coming out of the speakers (amplifier) when the machine is turned on. Maybe a chip? Everything else seems to be working except the toilet seat which seams to be a mofset that needs to be replaced. Any help would be great.
 
Start with the easy stuff first. Reseat all of the ribbon cables in the backbox and check to make sure all connectors are plugged in.
 
Thanks for the suggestion. I'll double check everything today again before I start looking for the hard fix. Have a Jurassic Park that the right flippers stopped working one day. I took out the flipper board, replaced fuse clips and did all kinds of stuff to fix those flippers. Turns out I had smashed the flipper switch pretty good on the right side taking the playfield out. Sometimes it is just a simple fix.
 
Well it doesn't seem like it's any of the connectors. It looks like there might be a problem with the board not getting the right amount of voltage. The display works and all the coils and switches seems to work as well. The game isn't resetting during play. Everything seems to work just fine, but there is no sound. Any ideas on what to try next?
 
It could be that the sound rom is bad or needs to be reseated. Find the sound rom and reseat it. If reseating it doesn't work make sure all of the speakers are connected.
 
Start with the easy stuff first. Re-seat all of the ribbon cables in the backbox and check to make sure all connectors are plugged in.
If re-seating them doesn't work, it's very possible that one or more of the connectors needs to be replaced. Here is an excerpt from Marvin's repair guide:

"The typical pinball connector (tin plated) has a life of 25 cycles. That's pretty low! But after 25 insertions or removals, the terminal pin's plating and retention (ability to retain shape) are compromised, and reliability will suffer. Header pins also have the same problem with plating (but not retention!) Add vibration into the formula, and the cycle life is probably even lower."
 
Pulled all the chips and checked the connectors. Pulled the CPU/sound board to get a better look at it. Seems like I found a capacitor that has a short (solder between the Pos and Neg connection. Not sure if that could cause the sound to not work at all, but will take care of it anyways. Wires to speakers are all okay, but maybe its time to think about changing that connector. Thanks for the help everyone.
 
Well its fixed. I too some of the solder off capacitor c108 that was causing a short and neutralized some acid leakage, installed new battery pack and it fired right up. Pretty much dumb luck that I found the short. I'm not what you would call a pro when it comes to electronics, just kept checking everything in that area with a dmm that I barely understand.

Anyone know if Kenny should pop back up after he dies? Mine kinda wobbles back up after he is hit with additional shots. Not sure if this is a weak spring or if that is how he is suppose to act?

Thanks for every ones help. Kept me motivated to figure it out. Now for that damn toilet lid...
